Based on the analysis of blended learning characteristics

a blended learning pro-cess model including preliminary analysis

learning activities design

blended evaluation was con-structed. Then

a blended learning case study was carried out by taking the Fourth Military Medical University Information Security course as an example. The implement methods of setting learning goal

selecting learning content

constructing learning environment

organizing learning activities and course evaluation

were described in detail. Lastly

from the effectiveness questionnaire

it could be shown that blended learning motivated the learners' enthusiasm significantly. In order to improve the learning performance

we proposed that blended learning activities must be flexible and adaptive，and integrate face-to-face learning with online learning effectively.
